影の時空的操作による身体表現創出に関する研究

摘要

In this research, our purpose is clarifying two things. One is the relationship between body action and somesthesia. The other is shadow attribute for working on this relationship. So, we performed some experiments on deforming body shadow depending on body action. First, we examined what attribute of the shadow enabled to work on the relationship between body action and somesthesia. As a result, it is suggested that it is important that shadow is displayed from one's feet. Next, we developed the shadow system which make possible to dynamically change the delay time between body action and motion of the shadow depending on body action. Consequently, it is found that this system enabled the participants to voluntarily generate continuous body action, and body action and somesthesia of them changed by this system.%本研究では，行為と身体感覚の関係性，及びこの関係性にはたらきかける影の特性を明らかにすることを目指し，身体の影を行為に合わせて変化させる実験及びデモを二，三行った．そこで，まずどのような身体の影の特徴によって行為と身体感覚の間にはたらきかけを導入することが可能になるのか調べた．その結果，自身の存在する足元から影が生じていることが重要である可能性が示唆された．
